Developer Meetings/20150127

To discuss

• Discuss Kilian's lightweight viewer project

Here are the issues that I still have with slite :
- start slite with one volume e.g. ./slite.sh white.nrrd
  - cannot correct window and level of viewer with mouse as it is the case in slicer 
  - when I select Lightbox view 1x2 then second half of viewer is black 

- load slite with two volumes e.g. ./slite.sh white.nrrd white.nrrd
  - both viewers act the same way (e.g. you move the slider in one viewer the other viewer moves two - show the same image , ...) 
   I believe the reason for doing it is that the Nodes associated with the first  viewer are changed to the same as the one of the second viewer
   e.g. of the first viewer
   sliceLogic().GetSliceCompositeNode().GetID() = vtkMRMLSliceCompositeNode1
  and after reading in the second volume changes to
    vtkMRMLSliceCompositeNodeRed

• Discuss migration to OpenGL2
